This is one of the lessons in Geometry that has endless possibilities when it comes to creativity in the class room. Distance Formula The history of the distance formula has been intertwined with the history of the Pythagorean Theorem.

If the equation does not contain x2, then solve the equation by getting the variables on one side and the numbers on the other side. For example, look at the diagonal of a square "d".

The focus then becomes the right triangle and the Pythagorean Theorem. When laying out a foundation, or constructing a square corner between two walls, construction workers will set out a triangle from three strings that correspond with these lengths.

In this progression, we start with the basic relationship of the side lengths of a triangle and move to giving students situations in which they can classify triangles as acute, obtuse, and right.

So, whether you're adding up pizzas or Richard Nixon masks, the Pythagorean theorem helps you relate the areas of any similar shapes. Good - Ok, how about anyone else. When you see a right triangle, realize the sides can represent the lengths of any portion of a shape, and the sides can represent variables in any equation that has a square.

Understand order of operations when solving an equation Plot ordered pairs on a coordinate grid. The derivation should look like the following: Well that's not what our group found. However, this standard is not focused on the distance formula. Ok, stop right there.

We also noticed that none of the lengths that we measured were ever larger than 5. Ok group 1, tell us what you found. Learning is focused on determining distances in right triangle situations. Now what happens when we add them together. Let's call the long side c 5the middle side b 4and the small side a 3.

I hope these high-level concepts make sense: Retrieved April 3,from Book Rags:. How We Use the Pythagorean Theorem in Everyday Life First, letâ€™s discuss the inventor of the theorem before how we use it.

Pythagoras of Samos is a very odd fellow but is very well known despite not have written anything in his lifetime so what we know about him comes from Historians and Philosophers. Review with the student The Pythagorean Theorem: Given a right triangle, the square of the hypotenuse is equal to the sums of the squares of the two sides or a2 + b2 = c2 Brainstorm with the student practical uses of the Pythagorean Theorem.

NBC's Lester Holt explores the path a defender must take in order to tackle a ball carrier, and how this distance - called the "angle of pursuit" - can be calculated by using the Pythagorean Theorem to find the hypotenuse of a right triangle, and the distance of a defender's angle of pursuit.

Pythagorean theorem ultimately works because all angles in a triangle must add up to degrees. If 1 angle is 90 degrees that guarantee the other two angles Angle A + Angle B = Angle A / 90 should be the percentage of how much Angle A is contributing to the required 90 degrees.

The Pythagorean Theorem is especially important to construction workers and architects.

It allows them to know the proper dimensions for building something safely and with stability. tsfutbol.com an application from real life in which knowing the Pythagorean Theorem would be useful.

Write a problem about the application to share with the class.
